I already knew about this phylogenetic tree (although I have always heard the common ancestor be called the "wild mustard", not wild cabbage), but the article was quite interesting.
I only wish that as a PSA, they had included the reminder to people over 30 years old who hate Brussels sprouts, that the delicious ones you can eat today are not the ones they hated in their youth, and if you haven't had sprouts in years you might want to give them a second try (salted, oiled and baked, not boiled or steamed of course!)
I think the sprouts trauma is the result of picking the wrong cooking method.
I was so surprised when I tried baked sprouts for the first time (use a really host cast iron skilet for even better results) that I started to believe that every vegetable can be delicious as long as you bake it!
